1. A tap dispenser comprising: a main body, said main body having a main body interior portion and an opposing main body exterior portion;a liquid flow pathway passing through said main body;a vent pathway passing through said main body, wherein air transport through said vent pathway is separated from liquid transport through said liquid flow pathway and wherein said vent pathway has a vent pathway inlet and an opposing vent pathway outlet;a vent valve operably engaged with said vent pathway outlet, wherein said vent valve is a duck bill valve;a valve cover extending from said vent pathway, wherein said valve cover at least partially encloses said vent valve, wherein said valve cover has a valve cover opening, wherein said valve cover comprises a terminal cover having a terminal cover periphery and a peripheral wall extending from said terminal cover periphery to said vent pathway outlet, wherein said terminal cover is above said vent valve, and wherein said valve cover has a valve cover drain wherein said valve cover drain has a valve cover drain invert elevation, and wherein said valve cover opening and said valve cover drain are substantially parallel;wherein said vent valve has an invert elevation and said valve cover opening has a valve cover opening invert elevation; anda liquid flow valve operably engaged with said liquid flow pathway;whereby air transport vented through said vent valve is retainable within said terminal cover thereby keeping a portion of said vent valve free of liquid. 2. A tap dispenser according to claim 1, wherein a portion of said liquid flow pathway and a portion of said vent pathway are in an annular relationship with one another. 3. A tap dispenser according to claim 1, wherein said liquid flow pathway has a liquid flow inlet proximal said main body and a liquid flow outlet distal to said main body wherein said liquid flow inlet is higher than said liquid flow outlet when said tap dispenser is in operable position. 4. A tap dispenser according to claim 1, wherein said vent pathway outlet is higher than said vent pathway inlet when said tap dispenser is in operable position. 5. A tap dispenser according to claim 1, wherein when said tap dispenser is in operable position said terminal cover is at an incline relative to a datum orthogonal to a gravitational liquid driving force. 6. A tap dispenser according to claim 1, wherein said valve has a valve opening at a valve opening invert elevation, wherein said valve opening invert elevation is higher than said valve cover drain invert elevation when said tap dispenser is in operable position. 7. A tap dispenser according to claim 1, wherein said vent pathway is substantially straight. 8. A tap dispenser according to claim 7, wherein said vent pathway has an open cross sectional area greater than about 6 mm2. 9. A tap dispenser according to claim 8, wherein said vent pathway inlet has a fluid pervious cover. 10. A tap dispenser according to claim 1, wherein when said vent valve has a valve opening at a valve opening invert elevation and wherein said valve cover opening has a valve cover opening invert elevation, wherein when said tap dispenser is in operable position said valve cover opening invert elevation is below said valve opening invert elevation and said valve cover opening extends above said valve opening invert elevation. 11. A tap dispenser according to claim 1, wherein said valve has a valve opening at a valve opening invert elevation, wherein said valve opening invert elevation is above said valve cover drain invert elevation when said tap dispenser is in operable position. 12. A tap dispenser according to claim 1, wherein said valve cover opening is substantially perpendicular to said vent pathway inlet. 13. A tap dispenser comprising: a main body, said main body having a main body interior portion and an opposing main body exterior portion;a liquid flow pathway passing through said main body;a vent pathway passing through said main body, wherein air transport through said vent pathway is separated from liquid transport through said liquid flow pathway, wherein said vent pathway has a vent pathway inlet and an opposing vent pathway outlet;a vent valve operably engaged with said vent pathway outlet, wherein said vent valve has a valve opening at a valve opening invert elevation, and wherein said vent pathway outlet has a valve cover extending from and at least partially enclosing said vent valve, wherein said valve cover has a valve cover opening and said valve cover has a valve cover drain wherein said valve cover drain has a valve cover drain invert elevation, and wherein said valve cover opening and said valve cover drain are substantially parallel, wherein said valve cover comprises a terminal cover having a terminal cover periphery and a peripheral wall extending from said terminal cover periphery to said vent pathway outlet, wherein when said tap dispenser is in operable position said terminal cover is at an incline relative to a datum orthogonal to a gravitational liquid driving force, and wherein a portion of said terminal cover is above said valve opening and is not in direct contact with said vent pathway outlet; anda liquid flow valve operably engaged with said liquid flow pathway. 14. A tap dispenser according to claim 13, wherein said vent valve is a duck bill valve. 15. A tap dispenser according to claim 13, wherein said liquid flow pathway has a liquid flow inlet proximal said main body and a liquid flow outlet distal to said main body wherein said liquid flow inlet is higher than said liquid flow outlet when said tap dispenser is in operable position. 16. A tap dispenser according to claim 13, wherein said vent pathway inlet has a fluid pervious cover. 17. A tap dispenser according to claim 13, wherein said valve cover opening has a valve cover opening invert elevation, wherein when said tap dispenser is in operable position said valve cover opening invert elevation is below said valve opening invert elevation and said valve cover opening extends above said valve opening invert elevation.
